To LLZZ whom) tm/ay concern.-

at Sandwich, in the cou'n'ty of De Kalb and State of Illinois, haveinvented certain new and useful Improvements in Beamers, of ywhich thefollowing is a specification.

IMy invention relates to certain improve-y ments in rearners designedespecially for. use

1o in removing the inwardly-pressed bur commonly producedv by ordinarytools used for cutting off wrought-iron gas, water, andV steam pipes. Incutting od the smaller sizes of these pipes, such as are more commonlyused, a rotary tool of some sort is usuallyem-- pleyed, the .action ofwhich is to crowd the metal inward toward the center-of the ,pipe

and when said metalis nally severed to leave' a very pronounced burforinwardly-projectzo ing ange, which reducesthediameter of the pipe and isother'vviseexceedingly.objection-v able.V It is my purpose to provideacheap and reliable device which maybe accurately centered upon the endof a pipe of.. this' sort and positively advanced Yinto the same to makea clean cut suici'ent to remove all of the bur above described; and tosuch end the invention consists in certain features of novelty belowdescribed and claimed.

In the drawings presented herewith, Figure l is a side elevation showingthe reamer secured to the end of a piece of pipe. Fig. 2 is a verticallongitudinal section of the same, the line of'section being shown at22'of Fig.

Fig. 4 is a detail section in plane 4 4; ofV Fig. 2, looking inthedirection ofthe arrow 4. Fig. 5 is a similar section in line 5-5 of1'Fig..4, looking in the directionof the'arrow 5. Fig

4o 6 is a perspective of adetachable plate. Fig.` 7 is a perspective ofa tool-carrier. Fig. 8 i-sl a perspective of a bearing-cup. Fig. 9 is asection in line 9 9'ofFig. l. Fig. 10 isa section in line l0 10 of Fig.1, and Fig. 11 is a view similar to Fig.r3 with all ,of the parts downtothe covering-plate removed.

Referring first to Figs. 1 and 2, apiece of gas-pipe is shown at A, uponwhich is secured a detachable collar B by means of set-screws 5o b b' 11?, an intermediate perforated bushing .annular ange.

n b3 beingshown in Fig. 2 to 'accommodate the Be it known that I,WILLIAM RADLEY, a citi zen of theUnited States of America, residing`pipe A, which is smaller than the smallest 'size which the collar willhold.L The removable collar is internally screw-threaded at b4 toreceive an externally-screw-threaded collar C, the threads c of whichfit those of the .removable collar, so that the rotation of the collar Cadvances it upon or withdraws it from the end of the pipe. This collar Cwill be called the feed-collar and the screw-threads c thereon thelead-screw. The feed-coliar C isprovided with'a radially-projectingannular flange c', toothed around its outer margin Aat c2., Against oneside of the iange c rests a plate-like extension d upon ahandleD,pivoted upon the feed-collar by means of said extension. It is securedin this position by means-of two clips ci'dfl, which project inwardslightly over the opposite side of the Between the clip d2 and theplated is'pivoted a'detent or pawl d3, (shown `moreclearly in Fig. 3,)one end of which, (Z4, A'is heldin engagement with thetooth of the liange by a spring d5 and the other end of which is formed into a handle-d6.By means of the 'handle D and detent the feed-collar may be rotated toadvance or Withdraw it from the removable collar B. The annular flange cis provided with a series of studs c3, upon the ends of which isremovably secured a perforated plate E by means of screws e.

The parts above referredv to make up an Figs'. 10 and 11, said Fig-llalso showingone of a series yot rectangular bushings Y, by

rmeans of which difterent sizes of dies may be accommodated. VThe die issecured inthe :stock by means of the perforated plate E above mentioned.This plate E is shown in perspective in Fig. 5. It is provided Lwith a'central-o eninfJr c' about the margin of which D e a e are two hookedlugs c2, the inner surfaces of the hooks of. which are inclined, as seenat e3.

ordinary die-stock, and so far as they have Upon this plateis removablysecured a bearing-cup F. (Shown in perspective in Fig. S and in4 varioussections in Figs, 2, 4,75, and 10.) Upon the insidepf the rimof thecupare two roo e eaav inwardly-projecting lugsff, adapted to engage withthe hooked lugs e2 and Wedge themselves between the hooks upon thelatter and the plate E to firmly secure the bearingcup to the plate. Thecup is provided with a handle f2, by means of which this attachment maybe effected. It also has a central perforation f3 in its bottom portion,in which is j ournaled a tool-carrier G. (Shown in perspective in Fig.7.) This tool-carrier has a cylindrical portion glitted to theperforation f3 in the cup, a notched flange g upon one side of saidcylindrical portion, adapted to rest upon the inside of the bottom ofthe cup, and a flat extension g2 upon the other side of said cylindricalportiomprovided Witha slit g3 to accom- Inodate a suitable reaming-tool.Upon this fiat extension is secured a handle H, (see Figs. 1,-2, and 3,)provided, with a slot h to fit over said extension and secured thereonby means of a split pin h,Which also secures the reamer in the slit.`Said reamer is seen at l and has an inwardly-extending tapered andsharpened end t' to do the cutting and a series of perforations i toreceive the pin h' and enable the reamer to be secured in a number ofpredetermined positions.

Fig. 9 shows an auxiliary device adapted to hold a wrench such as isneeded in the4 use of the die-stock,the same consisting of a lug s,projecting from the handle, and a button SQ pivoted upon the lug. Thelugis so proportioned in cross-section as to fit one of the openings ofthe Wrench, and the button is adapted to secure the Wrench upon the lug.This device aords a means of insuring the presence of the WrenchWhenever needed and avoiding ythe possibility of losing the same.

In the operation of the device above ldescribed the die-stock is securedto the pipe, and the reaming device is fastened upon the end of thestock by means of the bearing-cup F. The handle H is then turned torotate the reamin g-tool and the handle D oscillated to advance the feedstep by step and carry the ream erinto the end of the pipe. While ofcourse the reaming operation may be effected Without regard to thethreading of a pipe, yet Iconsider my invention particularly valuablebecause of the possibility of carrying on the two operationssimultaneously, or at leastin succession, Without removing the die-stockfrom the pipe. They preferred method is to secure the die-stock upon thepipe with the die in place and the reaming-tool attached and so adjustedas to finish its cutting when the die has completed the threadingoperation. The die-stock is then rotated to thread the pipe, the feedingdevices being loosened upon said pipe as soon as the die takes a properhold and the reamer being rotated by means of the handle H as soon as itcomes in contact with the bur extending into the pipe. By this means thereaming is effected Without any expenditure of time and with but littleadditional effort beyond that required to thread the pipe.

I claim as new and desire to secure by Letters Patentl.
